The widest H survey of accreting protoplanets around nearby transition disks
A. Zurlo, G. Cugno, M. Montesinos +6
The mechanisms of planet formation are still under debate. We know little about how planets form, even if more than 4000 exoplanets have been detected to date. Recent investigation…
NaCo polarimetric observations of Sz 91 transitional disk: a remarkable case of dust filtering
Karina Maucó, Johan Olofsson, Hector Canovas +10
We present polarized light observations of the transitional disk around Sz 91 acquired with VLT/NaCo at (1.7m) and (2.2m) bands. We resolve the disk and detect pola…
Flybys in protoplanetary discs: II. Observational signatures
Nicolás Cuello, Fabien Louvet, Daniel Mentiplay +14
Tidal encounters in star clusters perturb discs around young protostars. In Cuello et al. (2019a, Paper I) we detailed the dynamical signatures of a stellar flyby in both gas and d…
An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
Dust production in the debris disk around HR 4796 A
J. Olofsson, J. Milli, P. Thébault +21
Debris disks are the natural by-products of the planet formation process. Scattered or polarized light observations are mostly sensitive to small dust grains that are released from…
Evidence for a circumplanetary disk around protoplanet PDS 70 b
V. Christiaens, F. Cantalloube, S. Casassus +5
We present the first observational evidence for a circumplanetary disk around the protoplanet PDS~70~b, based on a new spectrum in the band acquired with VLT/SINFONI. We tested…
Thermal torque effects on the migration of growing low-mass planets
O. M. Guilera, N. Cuello, M. Montesinos +4
As planets grow the exchange of angular momentum with the gaseous component of the protoplanetary disc produces a net torque resulting in a variation of the semi-major axis of the…
